Abstract
The performance of dipole rectenna for microwave power transmission is very critical to the size and configuration of the dipole rectenna. Thus, it is important to verify the performance of dipole rectenna by comparing its performance in terms of simulation and experiment. This paper reports an experimental and computational investigation of coplanar strip (CPS) dipole rectenna for microwave power transmission. Rectenna consists of an antenna and a rectifier that involves a Schottky diode. CPS dipole antenna and rectenna are simulated using commercial software, so called Ansoft's HFSS and Designer. CPS dipole antenna as well as rectenna is fabricated on a copper coated polyimide substrate using an etching process. The characteristics of CPS dipole antenna are tested by using a pulse analyzer and spectrum analyzer under a 1.2 W microwave power incidence. Comparison of the simulation results with the experiments is made. The verified simulation approach for the CPS dipole rectenna will bring an effective design approach of rectennas for microwave power transmission.
